In tonght’s episode, Jess and Nick decide their own romantic fate in an epically zany finale that finds Schmidt (Max Greenfield) scheming to sabotage the arranged Indian wedding of his ex Cece (Hannah Simone) and Shivrang (Satya Bhabha)— with the help of an overzealous Winston (Lamorne Morris)!

Also along for the wild ride? Taylor Swift, who turns up as a wedding guest named Elaine.

“Taylor does a little bit of a riff on one of her songs,” reveals show creator Liz Meriweather. “I’m a huge fan of hers. I was fully geeking out. I didn’t go to meet her right away because I had to compose myself— there’s a 14-year-old girl inside of me.”

So how did Taylor do? According to Liz, “She kind of came and nailed it.” And considering the name of the highly-anticipated finale is titled, "Elaine's Big Day," we can't wait to see what happens.

To see what happens between Nick and Jess and check out Taylor’s acting chops, tune in to New Girl tonight at 9 p.m. ET on FOX.
